Weight training is touted as the cure for many ills. But if the goal is to lose belly fat, aerobic exercise is the only way to go, exercise scientists say.

We're not talking about muffin tops, the annoying bit of pudge that rolls over a woman's waistline and is featured in those strange Internet ads. Rather, this is gut fat lodged around internal organs, which could look like a beer belly from the outisde. It's considered a risk factor for diabetes, heart disease, and cancer.

I'm Michel Martin and you're listening to TELL ME MORE from NPR News. Later in the program, as the Eastern United States confronts a severe tropical storm, possibly hurricane, East Africa is still facing drought and famine. We'll get an update on the crisis that has already caused hundreds of thousands of people to flee their homes in the Horn of Africa. NPR's West Africa correspondent is on the scene and she'll tell us more but first it's time for our political chat.

Nervous investors - and these days that's most investors - were all ears this morning as Federal Reserve Chairman Ben Bernanke delivered a speech in Wyoming. The investors were listening for any clues about additional steps the Fed might take to shore up the sagging economy. Bernanke did not outline any big rescue plans, but he did say the Fed has tools it can use if necessary.

Yes, it was Albert Einstein who unified space and time together into a single, coherent whole. As a physicist I can say that was a pretty impressive feat, but as parent — slogging across interstate whatever on the last weekend of the summer — I have to ask: What's the big deal?

Anyone stuck in vacation traffic with kids in tow can tell you that Space and Time have always been unified but not in the wiggly, abstract sense my buddy Al Einstein was talking about.

Good morning, I'm David Greene. Two clowns walked into a Colorado jewelry store this week, guns blazing. The men wore white face paint, black lipstick and wigs. They pointed guns at employees and forced the owner to unlock his jewelry cases. The clown duo made off with the loot. But the joke was on them, Sonny's Rocks Jewelry Store in Denver does not display real jewelry. The display cases are full of fake gold and platinum, which is exactly what ended up in the clown's garbage bags.

Irish singer-songwriter James Vincent McMorrow has one of the most arresting voices of any young singer you're likely to hear this year: He's got the heartbreaking falsetto of a Justin Vernon (Bon Iver) and the raspy soul of a Ray LaMontagne, in a way that sounds both fragile and grand.

In 1995, when I was a sophomore in high school, an older, popular boy came out of the closet. He was taunted daily until he dropped out. I never saw him again.

Months later, a decidedly unpopular, more flamboyant boy was beaten in the schoolyard. I remember escorting him to the nurse's office. I remember the look of disgust on the nurse's face; I don't know whether this disgust was directed at the act of savagery, or at the bleeding boy himself, and his arm around my shoulder. I also remember thinking that soon it would be my turn, and sure enough it was.
